Dean G. Jarrett, Daniel Paseltiner, Shamith U. Payagala

We present the design, construction, calibration, and software development of a temperature monitoring system for resistance standards. The system supports 19 temperature probes. Over the range 295.15 K to 299.15 K (22 °C to 26 °C), we report an expanded
